BACKGROUND Background Information

An adjustable square is a multipurpose tool utilized in woodworking,metalworking, and other industries. Some typical uses of the adjustablesquare, among others, include measuring angles, scribing lines, servingas a depth gauge, and ensuring machinery is at a proper angle. Forexample, the adjustable square is typically used to measure ninetydegree angles and/or forty-five degree angles, scribe perpendicular andparallel lines, determine depth measurements of workpieces and/orcutting mechanisms, and determining whether to make adjustments tomachinery.

The adjustable square comes in various sizes and configurations,however, each size and configuration typically includes a blade, a body,and an engaging mechanism. The blade usually has a scale printed,embossed, or etched therein, and the body is typically movable along alength of the blade. The body is fixed at particular positions along thescale of the blade via the engaging mechanism. However, one drawbackassociated with having a movable body is that it is sometimes difficultto quickly and precisely position the body at various points along theblade.

The storage bore 14H is formed in thebody 14 proximate the rear region 14B of the body 14 and extendstransversely from the rear region 14B towards the front region 14A ofthe body 14. The upper section 15 has a diameter D1 and the lowerthreaded section 17 a diameter D2. As shown in FIG. 4, the diameter D1is larger than the diameter D2.

As shown in FIG. 7, the indexed bore 14I includes an upper section 19and a lower threaded section 21. The indexed bore 14I is formed in thebody 14 proximate the front region 14A of the body 14 and extendsvertically within the body 14 between the channel 14F and the secondside region 14D of the body 14. The upper section 19 has a diameter D3and the lower threaded section 21 a diameter D4. As shown in FIG. 7, thediameter D3 is larger than the diameter D4.

The first side surface 14J extends transversely from the front region14A towards the rear region 14B and is provided proximate the first sideregion 14C of the body 14. The second side surface 14K extendstransversely from the front region 14A towards the rear region 14B andis provided proximate the second side region 14D of the body 14. Whenthe blade 12 is operably engaged with the body 14, the first sidesurface 14J is oriented at an angle of ninety degrees relative to thecentral longitudinal axis X1 of the blade 12. When the blade 12 isoperably engaged with the body 14, the second side surface 14K isoriented at an angle of forty-five degrees relative to the centrallongitudinal axis X1 of the blade 12.

With primary reference to FIG. 1, FIG. 3, and FIG. 3A, the lockingmechanism 16 includes a front end 16A, a rear end 16B, an adjustmentmechanism 30, and a threaded post 32. The adjustment mechanism 30 isoperably engaged with the threaded post 32. The threaded post 32includes a clamping member 34 proximate the front end 16A of the lockingmechanism 16. The clamping member 34 includes a first beveled surface34A, a second beveled surface 34B, and a flat surface 34C, each of whichextend longitudinally between the first side region 14C and the secondside region 14D of the body 14.

The locking mechanism 16 is configurable between an unlocked position 38(FIG. 5B) and a locked position 40. The channel 14F is configured toreceive the threaded post 32 and the clamping member 34 of the lockingmechanism 16 such that the adjustment mechanism 30 is positioned withinthe aperture 14G, the threaded post 32 extends transversely through thechannel 14F, and the clamping member 34 is positioned within the channel14F proximate the slot 14E. The adjustment mechanism 30 is configured tomove the threaded post 32 and the clamping member 34 in a transversedirection to move the locking mechanism 16 between the unlocked position38 and the locked position 40 as more fully described below.

The blade 12 is configured to be releasably secured within the slot 14Evia the locking mechanism 16. More particularly, the second beveledsurface 34B of the clamping member 34 is configured to releasablycontact the second chamfered surface 22B of the groove 22 of the blade12. As such, when the locking mechanism 16 is in the unlocked position38, the second beveled surface 34B of the clamping member 34 is not incontact with the second chamfered surface 22B of the groove 22 allowingthe blade 12 to move through the slot 14E in the longitudinal direction.When the locking mechanism 16 is in the locked position 38, the secondbeveled surface 34B of the clamping member 34 is in contact with thesecond chamfered surface 22B of the groove 22 and the blade 12 is nolonger movable within the slot 14E.

With primary reference to FIG. 4 and FIG. 7, the indexing member 18 is ametal pin and includes a gripping portion 18A, a cylindrical section18B, a tapered section 18C, and a threaded end section 18D. Thecylindrical section 18B has a diameter D5 that is approximately the samedistance as length L2 of the minor axis X3 of the indexing aperture 24.The threaded end section 18D has a diameter D6 that is less than thediameter D5 of the cylindrical section 18B. The tapered section 18C hasa diameter that tapers from the diameter D5 of the cylindrical sectionto the diameter D6 of the threaded end section 18D. The indexing member18 is configurable between a stored position 42 (FIG. 4) and an indexedposition 44 (FIG. 7). When the indexing member is in the stored position42, the threaded end section 18D is threadingly engaged with the storagebore 14H. When the indexing member 18 is in the indexed position 44, thethreaded end section 18D is threadingly engaged with the indexed bore14I. The indexed bore 14I is provided at a distance of one inch from thefirst side surface 14J; however, the indexed bore 14I may be provided atany suitable distance. Although the indexing member 18 has beendescribed as being a metal pin having a threaded shaft 36, it is to beunderstood that the indexing member 36 may be any suitable mechanism.

Having described the structure of the combination square 10 and itsassociated components, reference is now made to FIG. 5A through FIG. 7to depict one exemplary use and operation of the combination square 10.As stated above, the indexing member 18 is configured to index the body14 at particular positions along the blade 12, such as, for example, atevery full inch along the length of the blade 12. This further allowsthe first series of notches 26 and the second series of notches 28 to beindexed to the body 14. In this example, the body 14 of the combinationsquare 10 is shown being indexed at the seven inch marking of thegraduations 20A.

With primary reference to FIG. 5A and FIG. 5B, the locking mechanism 16is shown being moved from the locked position 40 to the unlockedposition 38, the indexing member 18 is shown being removed from thestored position 42, and the body 14 is shown being moved such that thefirst side surface 14J moves from the seven and one half inch marking tothe six inch marking and the indexed bore 14I is vertically aligned withone of the plurality of indexing apertures 24 of the blade 12 located atthe seven inch marking.

To accomplish moving the locking mechanism from the locked position 40to the unlocked position 38, a user (not shown) of the combinationsquare 10 rotates the adjustment mechanism 30 of the locking mechanism16 in a direction indicated by arrow A. This causes the threaded post 32to move in a transverse direction toward the front region 14A of thebody 14, which, in turn, causes the second beveled surface 34B of theclamping member 34 to move away from the second chamfered surface 22B ofthe groove 22 such that the second beveled surface 34B of the clampingmember 34 is no longer in contact with the second chamfered surface 22B.This allows the body 14 to move in a longitudinal direction relative tothe blade 12. For example, the body 14 is movable in a directionindicated by arrow B (FIG. 5B) relative to the blade 12. As statedabove, and in this example, the body 14 is moved such that the firstside surface 14J moves from the seven and one half inch marking to thesix inch marking on the graduations 20A of the scale 20. Although thebody 14 was described as moving in the direction indicated by arrow B,it is to be understood that the body 14 is also movable in the oppositedirection to the direction indicated by arrow B.

To accomplish removing the indexing member 18 from the stored position42, the user rotates the gripping portion 18A of the indexing member 18in a direction indicated by arrow C (FIG. 5A). This rotates the indexingmember 18 until the threaded end section 18D is no longer threadinglyengaged with the storage bore 14H. The indexing member 18 is removedfrom the storage bore 14H and will be placed in the indexed position 44as explained below.

With primary reference to FIG. 5C and FIG. 5D, the user moves theindexing member into the indexed position 44. To accomplish this, theuser moves the indexing member 18 in a direction indicated by arrow D(FIG. 5D) to insert the indexing member 18 into the indexed bore 14I andthrough the indexing aperture 24 at the seven inch marking. The userrotates the gripping portion 18A in a direction indicated by arrow E(FIG. D), which, in turn, rotates the cylindrical section 18B, thetapered section 18C and the threaded end section 18D. As shown in FIG.7, the threaded end section 18D is rotated until a portion of thetapered section 18C contacts a portion of the slot 14E of the body 14.As the diameter D5 of the cylindrical section 18B is approximately thesame distance as length L2 of the minor axis X3 of the indexing aperture24, the body 14 and the blade 12 are fixed at the 7 inch marking.

The user rotates the adjustment mechanism 30 of the locking mechanism 16in a direction indicated by arrow F (FIG. 5D). This causes the threadedpost 32 to move in a transverse direction toward the rear region 14B ofthe body 14, which, in turn, causes the second beveled surface 34B ofthe clamping member 34 to move toward the second chamfered surface 22Bof the groove 22 such that the second beveled surface 34B of theclamping member 34 comes into contact with the second chamfered surface22B. This fixes the body 14 at the desired position relative to theblade 12.

With primary reference to FIG. 6, the combination square is shown beingused with a workpiece 46 having a top surface 46A and an edge 46B, and amarking instrument 50 having a tip 50A. In this example, the workpiece46 is a piece of wood and the marking instrument 50 is a pencil;however, the workpiece may be any suitable workpiece and the markinginstrument 50 may be any suitable marking instrument. In this example,the user utilizes the combination square 10 and the marking instrument50 to scribe a line parallel to, and three inches from, the edge 46B ofthe workpiece 46.

To accomplish this, the user positions the first side surface 14J of thebody 14 against the edge 46B of the workpiece 46. Since the body 14 hasbeen indexed to the scale 20 at the seven inch marking, the first sidesurface 14J of the body 14 is at the six inch marking of the scale 20and one of the first series of notches 26 is positioned at each fullinch marking of the scale 20. The user places the tip 50A of the markinginstrument 50 into one of the first series of notches 26 at the threeinch marking on the scale 20. The user scribes a line by simultaneouslymoving the combination square 10 and the marking instrument 50 in adirection indicated by arrow G.

Referring to FIG. 8, there is shown a second embodiment of an adjustablesquare in accordance with one aspect of the present disclosure. Theadjustable square, which may also be referred to as a double square, isgenerally indicated at 100. The double square 100 is substantiallyidentical to the combination square 10 in structure and function exceptthat the body 14 of the double square 100 is different than the body 14of the combination square 10. As shown in FIG. 8, the double square 10includes a second side surface 140K that is different than the secondside surface 14K of the combination square 10. Particularly, instead ofthe second side surface 14K being oriented at an angle of forty-fivedegrees relative to the central longitudinal axis X1 of the blade 12,the second side surface 140K is oriented at an angle of ninety degreesrelative to the central longitudinal axis X1 of the blade 12.

FIG. 9 depicts a method for indexing an adjustable square generally at900. The method 900 includes positioning a body of the adjustable squareat a precise known position along a scale of a blade of the adjustablesquare, which is shown generally at 902. The method 900 includesindexing, with an indexing member of the adjustable square, the body ofthe adjustable square at the precise known position, which is showngenerally at 904. The method 900 further includes aligning one of aplurality of indexing apertures formed in the blade with an indexed boreformed in the body, which is shown generally at 906. The method 900further includes inserting the indexing member into the indexed bore,which is shown generally at 908. The method 900 further includes passingthe indexing member through the one of the plurality of indexingapertures, which is shown generally at 910. The method 900 furtherincludes operably engaging a portion of the blade with the indexingmember to fix the body at the desired position, which is shown generallyat 912. The method 900 further includes indexing, with the indexingmember, the body relative to a series of notches formed in the blade andaligned with graduations of the scale which is shown generally at 914.

The indexing member 18, together with the plurality of indexingapertures 24, enables the body 14 of the adjustable square 10 to bequickly and precisely placed at desired positions to an even greateraccuracy and precision than that possible with other types of adjustablesquares.

Referring to FIG. 10-FIG. 24, there is shown a third embodiment of anadjustable square in accordance with one aspect of the presentdisclosure. The adjustable square, which may also be referred to as acombination square, is generally indicated at 210. The combinationsquare 210 includes a blade 212, a body 214, which may also be referredto as a head, a locking mechanism 16, an indexing member 218, and asliding tab 220.

The indexing member 218 is utilized for indexing the body 214 preciselyat known locations or positions along the blade 212. Since the body 214is indexed precisely at known locations or positions along the blade212, distances from the body 214 to points along the blade 212 areaccurately known and can be used while utilizing the combination square210. For example, the blade 212 may include measurement markingsextending along a length of the blade 212, and the body 214 may beindexable at certain points along the blade 212 where the distancebetween the measurement markings and the indexable points are accuratelyknown. If a user (not shown) of the combination square 210 desires tomove the body 214 from one position to another position along the blade212, the user can index the body 214 at the known location or positionand the distance from the body 214 to the measurement markings isaccurately known. This allows for greater precision when working withthe combination square 210 of the present disclosure.

With continued reference to FIG. 10-FIG. 24, the blade 212 is anelongated rectangular-shaped metal plate and is configured to beoperably engaged with the body 214 as more fully described below. Theblade 212 includes a first end 212A, a second end 212B, a first side212C, a second side 212D, a top 212E, and a bottom 212F. When the blade212 is operably engaged with the body 214, the first end 212A and thesecond end 212B define a longitudinal direction therebetween, the firstside 212C and the second side 212D define a transverse directiontherebetween, and the top 212E and the bottom 212F define a verticaldirection therebetween. The blade 212 further includes a centrallongitudinal axis X1 extending between the first end 212A and the secondend 212B of the blade 212. Although the blade 212 has been described asbeing an elongated rectangular-shaped metal plate, it is to beunderstood that the blade 212 may be any suitable shape and be made ofany suitable material.

The blade 212 includes a scale indicia 222, a groove 224 formed in aportion of the blade 12, a plurality of indexing apertures 226 formed inthe blade 212, a series of notches 228 formed in the blade 212. Thescale 222 includes graduations 222A arranged longitudinally along theblade 212. The graduations 222A include one-inch markings divided intoone-sixteenth inch segments provided adjacent the first side 212C of theblade 212, and one-inch markings divided into one-thirty second inchsegments provided adjacent the second side 212D of the blade 212.Although the graduations 222A have been described as utilizing U.S.customary units of measurement, the graduations 222A may utilize anysuitable units of measurement. Further, although the scale 222 has beendescribed as graduations 222A, it is to be understood that the scale 222may utilize any suitable identifying indicia.

The groove 224 extends longitudinally from the first end 212A of theblade 212 to the second end 212B of the blade 212. The groove 224includes a first chamfered surface 224A, a second chamfered surface224B, and a flat surface 224C, each of which extend longitudinally fromthe first end 212A of the blade 212 to the second end 212B of the blade212. The first chamfered surface 224A is provided between the first side212C of the blade 212 and the central longitudinal axis X1 of the blade212. The second chamfered surface 224B is provided between the secondside 212D of the blade 212 and the central longitudinal axis X1 of theblade 212. The flat surface 224C is provided generally along the centrallongitudinal axis X1 of the blade 212 and between the first chamferedsurface 224A and the second chamfered surface 224B.

Each of the plurality of indexing apertures 226 are substantiallysimilar in construction and, as such, only one of the plurality ofindexing apertures 226 will be described herein and will be designatedas 226A. For example, the indexing aperture 226A is substantially teardrop in shape with an oval shaped bottom proximate the second side 212Dand a point at a top side proximate the first side 212C. The indexingaperture 226A is provided at each inch marking and extends between thetop 212E and bottom 212F of the blade 212 and through the firstchamfered surface 224A, second chamfered surface 2246, and the flatsurface 224C of the groove 224. Stated otherwise, the plurality ofindexing apertures 226 are evenly spaced along a length of the blade212. Although the plurality of indexing apertures 226 have beendescribed as being teardrop in shape, it is to be understood that theplurality of indexing apertures 226 may be any suitable shape. Further,although the plurality of indexing apertures 226 have been described asbeing positioned at each one inch marking along the blade 212, it is tobe understood that the indexing apertures 226 may be placed in anysuitable position.

The series of notches 228 are substantially offset diamond-shapedcutouts formed between the top 212E of the blade 212 and the bottom 212Fof the blade 212. The first series of notches 228 extend longitudinallyalong the blade 212 and are provided between the first side 212C of theblade 212 and the central longitudinal axis X1 of the blade 212. Theseries of notches 228 are positioned such that one notch of the seriesof notches 228 is positioned at each sixteenth-inch marking, with eachodd numbered sixteenth facing toward the first side 212C and each evennumbered sixteenth facing towards the second side 212D.

The series of notches 228 are utilized for marking purposes as morefully described below. Although the series of notches 228 have beendescribed as being offset diamond-shaped cutouts, it is to be understoodthat the series of notches 228 may be any suitable shape. Further,although the series of notches 228 have been described as beingpositioned at the one-sixteenth inch marking, along the blade 212, it isto be understood that the series of notches 228 may be placed in anysuitable position.

The body 214 includes a front region 214A, a rear region 214B, a firstside region 214C, and a second side region 214D. The body 214 furtherincludes a first slot 214E, a second slot 214F, a region 214G, an ovalchannel 214H, a top surface 214J, a bottom surface 214K, and an indexedbore 214L.

The first slot 214E is formed in the body 214 proximate the front region214A, the first side region 214C, and the second side region 214D of thebody 214 and extends transversely from the front region 214A towards therear region 214B of the body 214. The second slot 214F is formed in thebody 214 proximate the rear region 214B, the first side region 214C, andthe second side region 214D of the body 214 and extends transverselyfrom the front region 214A towards the rear region 214B of the body 214.A region 214G is formed between a top surface 214J and a bottom surface214K.

The oval channel 214H is located on a top surface 214L of the body andis generally oval in shape. The oval channel 214H and the second slot214F permit the sliding tab 220 to move within the body 214. Referringspecifically to FIG. 11, a partially exploded view of the sliding tab220 is shown. The sliding tab 220 comprises three parts, a body 220A, alocking pin 220B and a restrictor 220C. The body 220A generally has abulbous portion 220D, a recess 220E and a through hole 220F. The bulbousportion 220D is generally semicircular and is operative to be grasped bya user during operation as will be discussed later. The recess 220E isoperative to fit the restrictor 220C within it while the through hole isoperative to accept the locking pin 220B. The locking pin 220B isgenerally cylindrical in shape while the restrictor is shown as an Xshape. While the body 220A, locking pin 220B and restrictor 220C havebeen described as being separate components, it is to be understood thatthey may be different shapes to effectuate the same result. Further,while the body 220A, locking pin 220B and restrictor 220C have beendescribed as separate pieces, they may be operatively connected and maybe otherwise integrally formed with the body 214.

Referring specifically to FIG. 13, a cross-sectional view of the body214 of the adjustable square 210 along line 13-13 of FIG. 12 is shown.Specifically, this view shows the second recess 212J accepting therestrictor 220C and a portion of the body 220A so as to prevent the body220A from plunging deeper into the body 214. Simultaneously, this allowsthe locking pin 220B to freely move as a result of moving the body 220Ain a longitudinal manner.

With primary reference to FIG. 10 and FIG. 12, the locking mechanism isidentical to the locking mechanism 16 of the first embodiment. This maybe seen in FIG. 3 of the first embodiment most completely. Furtherincluded with the locking mechanism is an adjustment mechanism 30, and athreaded post 32. The adjustment mechanism 30 is operably engaged withthe threaded post 32. The threaded post 32 includes a clamping member 34proximate the front end 16A of the locking mechanism 16. The clampingmember 34 includes a first beveled surface 34A, a second beveled surface34B, and a flat surface 34C, each of which extend longitudinally betweenthe first side region 214C and the second side region 214D of the body214. The first beveled surface 34A, the second beveled surface 34B, andthe flat surface 34C are complementary in shape to the first chamferedsurface 224A, the second chamfered surface 224B, and the flat surface224C of the groove 224 of the blade 212.

The locking mechanism 16 is configurable between an unlocked position 38and a locked position 40. A channel within the body 214 (not shown inthis embodiment but substantially identical to 14F) is configured toreceive the threaded post 32 and the clamping member 34 of the lockingmechanism 16 such that the adjustment mechanism 30 is positioned withinan aperture of the body 214, and the threaded post 32 extendstransversely through the channel, while the clamping member 34 ispositioned within the channel proximate the slot 214E. The adjustmentmechanism 30 is configured to move the threaded post 32 and the clampingmember 34 in a transverse direction to move the locking mechanism 16between the unlocked position 38 and the locked position 40 as morefully described below.

The blade 212 is configured to be releasably secured within the slot214E via the locking mechanism 16. More particularly, the second beveledsurface 34B of the clamping member 34 is configured to releasablycontact the second chamfered surface 224B of the groove 224 of the blade212. As such, when the locking mechanism 16 is in the unlocked position38, the second beveled surface 34B of the clamping member 34 is not incontact with the second chamfered surface 224B of the groove 224allowing the blade 212 to move through the slot 214E in the longitudinaldirection. When the locking mechanism 16 is in the locked position 38,the second beveled surface 34B of the clamping member 34 is in contactwith the second chamfered surface 224B of the groove 224 and the blade212 is no longer movable within the slot 214E.

Further shown on the adjustable square 210 is an angle α. The angle α isthe complementary angle to the angle between the front region 214A andthe second side region 214D. As will be discussed with respect tooperation the adjustable square 210 is operable to layout dovetailjoints (or simply “dovetails”). When laying out dovetails, it is optimalto know lay out the dovetails with a specific ratio. Common ratios are1:6, 1:7 and 1:8. In this instance, the ratios correspond to one unithorizontal to six, seven or eight units, respectively, drawn horizontal.While an exemplary embodiment of the 1:8 is shown, any such layout ispossible. In the exemplary embodiment of 1:8, a has a value of about 7degrees. In the exemplary embodiment of 1:7, a has a value of about 8degrees. While in an alternative embodiment of 1:6, a has a value ofabout 9.5 degrees.

Continuing to FIG. 14, a cross-sectional view of the body 214 of theadjustable square 210 along line 14-14 of FIG. 12 is shown. The indexedbore 214L includes the indexing member 218. The indexing member 218includes a first end 218A and a second end 218B. Proximate where theindexing member 218 meets the indexed bore 214L is a spring cap 218C.Further there is a tapered region 218D proximate the second end 218Bthat has a diameter D7. The diameter D7 is slightly smaller than a firstdiameter D8 of the indexed bore 214L. Laterally above the tapered region218D is an intermediate diameter D9 region 218E, a poppet region 218Fwith a diameter D10 along with a spring 218G. The indexed bore 214L hasa second diameter D11 that is larger than the first diameter D8 butslightly larger than the diameter D10. Generally speaking, the indexedbore 214L is formed in the body 214 proximate the front region 214A ofthe body 214. Further, there is a distance when the spring 218G is notdepressed shown as D12.

As will be discussed further with respect to operation, the indexingmember 218 at its second end 218B at the tapered region 218D isoperative to nest and hold within the indexing apertures 226 (FIG. 18).The tapered region 218D will engage the indexing aperture 226 and isoperative to retain the precise location of the indexing aperture 226chosen and when the locking mechanism 16 is engaged as will be discussedwith respect to operation. The tapered region 218D will not interfacewith the blade 212 to prevent movement of the body 214 when slidingalong the groove 224 of the blade 212. The tapered region 218D willinstead slide along the top 212E of the blade 212 until it is depressedand makes contact with at least a portion of the indexing aperture 226.When the tapered region 218D is in contact with at least a portion ofthe indexing aperture 226, movement of the body 214 with respect to theblade 212 may cease. In this figure the indexing aperture 226 is notengaged with the tapered region 218D as the indexing aperture 226 is notaligned at the moment and instead the aligned with the groove 224 of theblade 214 alone.

Having described the structure of the combination square 210 and itsassociated components, reference is now made to FIG. 15 through FIG. 24to depict one exemplary use and operation of the combination square 210.As stated above, the indexing member 218 is configured to index the body214 at particular positions along the blade 212, such as, for example,at every full inch along the length of the blade 212. This furtherallows the series of notches 28 to be properly indexed to the body 214.

With primary reference to FIG. 15 and FIG. 16, the locking mechanism 16is shown to be loosened 38 or otherwise not engaged. The indexing member218 is shown in an unengaged position and may be depressed in thedirection of arrow H in order to attempt to engage the indexing member218 within the indexing aperture 226. In order to depress the indexingmember 218 spring bias must be overcome. If there is no indexingaperture 226 at the precise location, the body 214 is free to move.Specifically, the body 214 is then able to be slid along the blade 212in the direction of arrow J. Referring to FIG. 16 specifically, thetapered region 218D will not interface in order to prevent movement whenengaged with the groove 224 and may slide freely in the direction ofarrow J. The tapered region 218D will slide along the top 212E of theblade 214 until it is depressed and makes contact with an indexingaperture 226, as seen later with respect to FIG. 18. While shown hereinas the indexing member 218 being depressed in a vertical manner toengage or attempt to engage with the indexing aperture 226, alternativeembodiments allow for an axial depression depending on the desiredimplementation of the combination square 210.

Referring specifically to FIG. 17, FIG. 18 and FIG. 19, a furtheroperational view is shown. The indexing member 218 is depressed in thedirection of arrow K to prevent the body 214 to move relative to theblade 212. The body 214 is then no longer moved as the blade 212 is heldin engagement with the body 214. The tapered region 218D interfaces inorder to prevent movement when engaged with the indexing aperture 226and prevent free movement. The tapered region 218D will make contactwith indexing aperture 226A while the spring is depressed to a distanceof D13 as shown in FIG. 18. The tapered region 218D allows the indexingmember to be held in engagement with the indexing aperture 226. Theindexing member 218 is in a first position when the indexing member 218is disengaged with the blade 212 and a second position when the indexingmember 218 is engaged with the blade 212.

Then, the user rotates the adjustment mechanism 30 of the lockingmechanism 16 in a direction indicated by arrow F (FIG. 17). This causesthe threaded post 32 to move in a transverse direction toward the rearregion 214B of the body 214, which, in turn, causes the second beveledsurface 234B of the clamping member 234 to move toward the secondchamfered surface 224B of the groove 224 such that the second beveledsurface 34B of the clamping member 34 comes into contact with the secondchamfered surface 224B. This fixes the body 214 at the desired positionrelative to the blade 212. The user may then move the sliding tab 220 toa neutral position via arrow L so as to be flush with the first sideregion 214C of the body 214.

Referring to FIG. 20, a further operational view is shown. A saw blade48 or other such similarly situated device when the device is engaged atthe one inch marking may act as a square in order to move the blade 48to be a perfect 90 degree edge. The saw blade 48 may then be squared upand adjusted to a proper depth via arrow M.

Continuing to FIG. 21, FIG. 22, FIG. 23 and FIG. 24, further operationalviews are shown. Specifically, the user may desire to make dovetailjoints or other similarly situated joining devices out of wood. First,the user may draw a starting line with the pencil or similarly situatedmarking device 50 on the edge 46B of a work piece 46 along direction ofarrow N. A series of the lines will be made on the edge 46B. These lineswill be easy to keep straight by moving the sliding tab 220 in thedirection of arrow P to move the body 220A of the sliding tab 220 inengagement with the edge 46B of the work piece 46. This may be furtherevidenced by FIG. 22 showing line 22-22 of FIG. 21 with the body 220A ofthe sliding tab 220 firmly against the work piece 46.

Continuing on to FIG. 23, a baseline 52 has been marked or otherwisestruck. Then, the second side region 214D is abutted to be flat againstthe board with the rear region 214B facing a left side 46C of the workpiece 46. A series of lines may then be drawn as the left facing anglesmay then be marked via arrow Q as shown as lines 54. Further, the usermay then move the sliding tab 220 via arrow R in order to further bracethe square 210 against the work piece 46.

Then, when the right side 46D is reached, the tool 210 may be flippedover so that the rear region 214B faces the right side 46D. Acorresponding number of right facing angles may then be marked in asimilar fashion. The resultant shape would be the two angled linesforming that of a dovetail joint and would be able to be removed with achisel or other known cutting device.

With primary reference to FIG. 24, the combination square 210 is shownbeing used with a workpiece 46 having a top surface 46A and an edge 46B,and the marking instrument 50 having the tip 50A. In this example, theuser utilizes the combination square 210 and the marking instrument 50to scribe a line parallel to, and a quarter inch from, the edge 46B ofthe workpiece 46.

To accomplish this, the user positions the first side surface 214C ofthe body 214 against the edge 46B of the workpiece 46. Since the body214 has been indexed to the scale 222 at the four inch marking, thefirst side surface 214C of the body 214 is at the three inch marking ofthe scale 222 and one of the notches 228 is positioned at each full inchmarking of the scale 222. The user places the tip 50A of the markinginstrument 50 into one of the series of notches 228 at the two and threequarters inch marking on the scale 222. The user scribes a line bysimultaneously moving the combination square 210 and the markinginstrument 50 in a direction indicated by arrow G.

Various inventive concepts may be embodied as one or more methods, ofwhich an example has been provided. The acts performed as part of themethod may be ordered in any suitable way. Accordingly, embodiments maybe constructed in which acts are performed in an order different thanillustrated, which may include performing some acts simultaneously, eventhough shown as sequential acts in illustrative embodiments.

While various inventive embodiments have been described and illustratedherein, those of ordinary skill in the art will readily envision avariety of other means and/or structures for performing the functionand/or obtaining the results and/or one or more of the advantagesdescribed herein, and each of such variations and/or modifications isdeemed to be within the scope of the inventive embodiments describedherein. More generally, those skilled in the art will readily appreciatethat all parameters, dimensions, materials, and configurations describedherein are meant to be exemplary and that the actual parameters,dimensions, materials, and/or configurations will depend upon thespecific application or applications for which the inventive teachingsis/are used. Those skilled in the art will recognize, or be able toascertain using no more than routine experimentation, many equivalentsto the specific inventive embodiments described herein. It is,therefore, to be understood that the foregoing embodiments are presentedby way of example only and that, within the scope of the appended claimsand equivalents thereto, inventive embodiments may be practicedotherwise than as specifically described and claimed. Inventiveembodiments of the present disclosure are directed to each individualfeature, system, article, material, kit, and/or method described herein.In addition, any combination of two or more such features, systems,articles, materials, kits, and/or methods, if such features, systems,articles, materials, kits, and/or methods are not mutually inconsistent,is included within the inventive scope of the present disclosure.

All definitions, as defined and used herein, should be understood tocontrol over dictionary definitions, definitions in documentsincorporated by reference, and/or ordinary meanings of the definedterms.

The articles “a” and “an,” as used herein in the specification and inthe claims, unless clearly indicated to the contrary, should beunderstood to mean “at least one.” The phrase “and/or,” as used hereinin the specification and in the claims (if at all), should be understoodto mean “either or both” of the elements so conjoined, i.e., elementsthat are conjunctively present in some cases and disjunctively presentin other cases. Multiple elements listed with “and/or” should beconstrued in the same fashion, i.e., “one or more” of the elements soconjoined. Other elements may optionally be present other than theelements specifically identified by the “and/or” clause, whether relatedor unrelated to those elements specifically identified. Thus, as anon-limiting example, a reference to “A and/or B”, when used inconjunction with open-ended language such as “comprising” can refer, inone embodiment, to A only (optionally including elements other than B);in another embodiment, to B only (optionally including elements otherthan A); in yet another embodiment, to both A and B (optionallyincluding other elements); etc. As used herein in the specification andin the claims, “or” should be understood to have the same meaning as“and/or” as defined above. For example, when separating items in a list,“or” or “and/or” shall be interpreted as being inclusive, i.e., theinclusion of at least one, but also including more than one, of a numberor list of elements, and, optionally, additional unlisted items. Onlyterms clearly indicated to the contrary, such as “only one of” or“exactly one of,” or, when used in the claims, “consisting of,” willrefer to the inclusion of exactly one element of a number or list ofelements. In general, the term “or” as used herein shall only beinterpreted as indicating exclusive alternatives (i.e. “one or the otherbut not both”) when preceded by terms of exclusivity, such as “either,”“one of,” “only one of,” or “exactly one of.” “Consisting essentiallyof,” when used in the claims, shall have its ordinary meaning as used inthe field of patent law.

As used herein in the specification and in the claims, the phrase “atleast one,” in reference to a list of one or more elements, should beunderstood to mean at least one element selected from any one or more ofthe elements in the list of elements, but not necessarily including atleast one of each and every element specifically listed within the listof elements and not excluding any combinations of elements in the listof elements. This definition also allows that elements may optionally bepresent other than the elements specifically identified within the listof elements to which the phrase “at least one” refers, whether relatedor unrelated to those elements specifically identified. Thus, as anon-limiting example, “at least one of A and B” (or, equivalently, “atleast one of A or B,” or, equivalently “at least one of A and/or B”) canrefer, in one embodiment, to at least one, optionally including morethan one, A, with no B present (and optionally including elements otherthan B); in another embodiment, to at least one, optionally includingmore than one, B, with no A present (and optionally including elementsother than A); in yet another embodiment, to at least one, optionallyincluding more than one, A, and at least one, optionally including morethan one, B (and optionally including other elements); etc.

When a feature or element is herein referred to as being “on” anotherfeature or element, it can be directly on the other feature or elementor intervening features and/or elements may also be present. Incontrast, when a feature or element is referred to as being “directlyon” another feature or element, there are no intervening features orelements present. It will also be understood that, when a feature orelement is referred to as being “connected”, “attached” or “coupled” toanother feature or element, it can be directly connected, attached orcoupled to the other feature or element or intervening features orelements may be present. In contrast, when a feature or element isreferred to as being “directly connected”, “directly attached” or“directly coupled” to another feature or element, there are nointervening features or elements present. Although described or shownwith respect to one embodiment, the features and elements so describedor shown can apply to other embodiments. It will also be appreciated bythose of skill in the art that references to a structure or feature thatis disposed “adjacent” another feature may have portions that overlap orunderlie the adjacent feature.

Spatially relative terms, such as “under”, “below”, “lower”, “over”,“upper”, “above”, “behind”, “in front of”, and the like, may be usedherein for ease of description to describe one element or feature'srelationship to another element(s) or feature(s) as illustrated in thefigures. It will be understood that the spatially relative terms areintended to encompass different orientations of the device in use oroperation in addition to the orientation depicted in the figures. Forexample, if a device in the figures is inverted, elements described as“under” or “beneath” other elements or features would then be oriented“over” the other elements or features. Thus, the exemplary term “under”can encompass both an orientation of over and under. The device may beotherwise oriented (rotated 90 degrees or at other orientations) and thespatially relative descriptors used herein interpreted accordingly.Similarly, the terms “upwardly”, “downwardly”, “vertical”, “horizontal”,“lateral”, “transverse”, “longitudinal”, and the like are used hereinfor the purpose of explanation only unless specifically indicatedotherwise.

Although the terms “first” and “second” may be used herein to describevarious features/elements, these features/elements should not be limitedby these terms, unless the context indicates otherwise. These terms maybe used to distinguish one feature/element from another feature/element.Thus, a first feature/element discussed herein could be termed a secondfeature/element, and similarly, a second feature/element discussedherein could be termed a first feature/element without departing fromthe teachings of the present invention.
